Kapteyn's Star

Kapteyn’s Star is a class M1 red dwarf about 12.76 light years from Earth in the southern constellation of Pictor, and the closest halo star to the Solar System. With a magnitude of nearly 9 it is visible through binoculars or a telescope from Earth. Its diameter is 30% of the Sun, but its Luminosity just 0,1% L0. It may have once been part of the globular cluster Omega Centauri, itself a likely dwarf galaxy swallowed up by the Milky Way in the distant past.

Kapteyn’s Star is host to two low-mass planets, Kapteyn b and Kapteyn c. Kapteyn B is a Lava Siper-Earth, while Kapteyn C is Super-Earth Iron Planet.
